Government ministers arrive in Paris today as climate talks enter their second week. The ministers add high-level influence to the climate negotiations and can help unlock critical elements of a new climate deal.
“It’s going to be quite a sprint for ministers to secure a strong deal by Friday,” said Tasneem Essop, head of WWF’s delegation to the COP21 climate talks. “The French presidency now has the responsibility to take us to the finish line.”
The rainfall and snowpack so far this autumn have been encouraging, but the stubborn reality is that California is still mired in drought. While farmers from Bakersfield to Fresno to Redding are screaming about water quotas, California residents say they are doing what they can, from pulling out grass lawns to capturing what little rainwater exists.
Climate change is likely to have far-reaching impacts on food security throughout the world, especially for the poor and those living in tropical regions, according to a new international report that includes three co-authors from the National Center for Atmospheric Research (NCAR).
Northwestern University neuroscientists now can read the mind of a fly. They have developed a clever new tool that lights up active conversations between neurons during a behavior or sensory experience, such as smelling a banana. Mapping the pattern of individual neural connections could provide insights into the computational processes that underlie the workings of the human brain.
In a study focused on three of the fruit fly’s sensory systems, the researchers used fluorescent molecules of different colors to tag neurons in the brain to see which connections were active during a sensory experience that happened hours earlier.
Los desiertos de alimentos, esas grandes extensiones de zonas urbanas y rurales vacíos de fruta fresca y verduras, son una epidemia que va en aumento y que afecta a más de 23,5 millones de personas a nivel nacional en los EEUU. Afectan desproporcionadamente a los ocupantes pobres de los barrios de bajos ingresos, los desiertos de alimentos son el resultado de la falta de acceso a una alimentación saludable.
Astronomers harnessing the combined power of NASA's Hubble and Spitzer space telescopes have found the faintest object ever seen in the early universe. It existed about 400 million years after the big bang, 13.8 billion years ago.
The team has nicknamed the object Tayna, which means "first-born" in Aymara, a language spoken in the Andes and Altiplano regions of South America.
Though Hubble and Spitzer have detected other galaxies that are record-breakers for distance, this object represents a smaller, fainter class of newly forming galaxies that until now had largely evaded detection. These very dim objects may be more representative of the early universe, and offer new insight on the formation and evolution of the first galaxies.
